| 摘 要： | 应用AFLP技术对我国4种主要养殖扇贝进行了遗传分析.虾夷扇贝、海湾扇贝、华贵栉孔扇贝、栉孔扇贝4种养殖扇贝群体中,种内遗传相似度依次分别为0.841 5,0.786 3,0.719 0和0.673 1,香侬氏指数分别为43.52,58.87,80.16和92.83,栉孔扇贝和华贵栉孔扇贝的遗传多样性水平明显高于海湾扇贝和虾夷扇贝;AFLP标记共享位点分布表明,在4种扇贝中栉孔扇贝与华贵栉孔扇贝之间的共享位点最多,同时4种扇贝的种间遗传相似度也以栉孔扇贝和华贵栉孔扇贝之间为最高(0.769 5),海湾扇贝和虾夷扇贝之间为最低(0.662 6),揭示所研究的几种扇贝中栉孔扇贝和华贵栉孔扇贝的遗传关系最近(遗传距离为0.262 1);找到了21个种内特异性AFLP标记和种间共享标记,可用于种质鉴定和分子辅助分类.

| Abstract: | The AFLP technology was used to analyse the genetic diversity of four scallops, Patinopecten yessoensis, Argopecten irradians, Chlamys nobilis and C. farreri.The genetic similarity index of the four species is 0.841 5, 0.786 3, 0.719 0 and 0.673 1, while Shannon index is 43.52, 58.87, 80.16 and 92.83,respectively.The results show that the two native species,C. farreri and C. nobilis, have higher level of the genetic diversity than the two introduced species, A. irradians and P. yessoensis.The results also show that C. nobilis and C. farreri shared the most common loci. The genetic distance indicates that C. nobilis and C. farreri are closely related. Moreover, out of 510 AFLP markers, 21 specific bands are found to distinguish the four species scallop and these markers may be applied for germplasm characterization and molecular assistant classification in scallops. |
